How to split strings in an array into arrays of characters

Question

I'm making a simple program that jumbles up the letters in words. I want to split every word into an array, within the existing one. i.e.

    ['hello','my','name','is','Anders']

    [['h','e','l,'l','o'],['m','y'],['n','a','m','e'],['i','s'],['A','n','d','e','r','s']

So how would I go about doing this?

Where are you stuck? Do you not know how to transform an array by transforming each element? Do you not know how to split a string into its component characters? — user663031

Here:

var arr = ['hello','my','name','is','Anders', '🍺'];
var res = arr.map(e => e.split(""));

console.log(res)

You could use the spread syntax ... and take single characters.

var array = ['hello','my','name','is','Anders', '🍺'],
    splitted = array.map(s => [...s]);
    
console.log(splitted);

You can use the Array.map function and the String.split, so your code would be like this:

phrase = ['hello','my','name','is','Anders']
phrase.map(x => x.split(""))

Can you give an example where this code could fail?

Any supplementary-plane character such as 💩.
